Description aheverle 2017-11-07 19:00:59 UTC

Description of problem:
When using the libsmbclient smbc_statvfs_ctx function call on a Windows 2016 or Windows 2012 R2 server that has the SMB1/CIFS features disabled through the server manager, the sizes are all returned as zero.



Version-Release number of selected component (if applicable):


How reproducible:
All the time. 

Steps to Reproduce:
You can easily repeat this using the teststatvfs example from the Samba code base. The attached log uses teststatvfs and then uses the smbclient command to show the difference. The smbclient command uses the Samba4 client code, where as libsmbclient uses Samba3 and other bridge code to make it work. It is a mess.

Actual results:
# ./teststatvfs
Path: smb://10.0.0.1/SHARE/
Workgroup: [WORKGROUP] 
Username: [root] <username>
Password: <password>
Workgroup: [WORKGROUP]

If upstream will pick it up in time we can reconsider adding it to RHEL 7.5.

Sanity Only here.
